Dense packed cellulose insulation - the how and why it is great for older homes and buildings.
Insulation is inherently green because it increases the energy efficiency of homes and buildings. But are some insulations "greener" than others?
When the "Energy Crisis" of the 1970's sent homeheating and cooling costs soaring, demand for building insulation rose right along with the prices of oil, gas,and electricity.
Blown-in cellulose is a popular alternative to fiberglass insulation. According to insulation specialist, Richard Applegate, cellulose is a natural wood product, and 75 percent of what it's made from is recycled newspaper.
New research from the IARC shows “there is now sufficient evidence that formaldehyde causes nasopharyngeal cancer in humans...”
These recommendations are cost-effective levels of insulation based on the best available information on local fuel material costs and weather conditions.
Demonstrations using transparent plastic "walls" inevitably show the superiority of cellulose in filling existing walls with many fewer gaps and voids than mineral fiber materials.
Molds are microscopic fungi that live on organic matter. Most molds produce spores, which can be air-borne, water-borne, or insect-borne and are highly adapted to grow and rapidly reproduce under the right conditions.
When you consider performance and safety factors, the balance swings to cellulose building insulation.
This document covers the composition and physical properties of Applegate cellulose insulations. This information is relevant to the specification of Applegate Insulation in ceilings, attics, walls, floors and other areas.
